If it is the lighter shades, I'd back it in white or silver. It'll be more brilliant. That'swhat I did for my lid since it's flourescent yellow and green metallic.
Its fluro green and fluro yellow. I will have to stop at the hobbyshop. Plus i want to do a little something extra anyways....I'm going to back in silve and a little blue will get thrown in there. Wait. Can i paint a light blue on top of the green?
um, it'll make the green darker. I backed mine with silver and it was nice. It was brighter with white. Either way, doesn't matter for me. My bodies get destroyed after a day of racing.
